Fengyun 2-07[2] orFY-2-07 (Chinese:风云二号07 meaningWind Cloud 2-07), also known asFengyun-2F orFY-2F, is a Chineseweather satellite operated by China'sNational Satellite Meteorological Centre.[3] Part of theFengyun programme, it was the sixthFengyun 2 geostationary satellite to be launched.[4]
Fengyun 2-07 was launched by aLong March 3A carrier rocket, with theserial number Y22,[5] flying fromLaunch Area 3 at theXichang Satellite Launch Centre. The launch took place on 13 January 2012 at 00:56 UTC, and resulted in the successful deployment of the satellite into ageosynchronous transfer orbit. After raising itself into its operationalgeostationary orbit, by means of anFG-36apogee motor,[4] the satellite will be positioned at alongitude of 86.5 degrees East.[6]
At launch, Fengyun 2-07 had a mass of 1,369 kilograms (3,018 lb), however by the time it reaches its operational orbit, this will have decreased to 536 kilograms (1,182 lb), partly through jettisoning the FG-36. The spacecraft is cylindrical, with a diameter of 2.1 metres (6 ft 11 in), and a length of 4.5 metres (15 ft) fully deployed. It is spin-stabilised at a rate of 100 rpm,[4] and carries a five-channelStretched Visible and Infrared Spin Scan Radiometer, or S-VISSR, capable of producing visible light and infrared images of the Earth. The S-VISSR will return visible-light images with a resolution of 1.25 kilometres (0.78 mi), and infrared images with a resolution of 5 kilometres (3.1 mi). It will produce a full-disc image every thirty minutes, as well as imaging smaller areas of interest.[7] In addition to S-VISSR, Fengyun 2-07 also carries an x-ray detector to monitor theSun, and detectsolar flares.[5]
